- Hy-Brasil
- In Celtic myth a mysterious island in the Atlantic thought by some to be the last vestiges of Atlantis to which fled the leaders of the Tuatha Dé Danaan after their defeat by the Milesians. Hy-Brasil was shown on maps of the Atlantic even after the discovery of America. Whether this is in any way related to the Nordic Yggdrasil has not yet been determined.
